APPARATUS FOR DECOMPOSING METALLIC SALTS AND DESULPHURlZlNG ORES.

SPECIFICATION forming part of Letters Patent No. 416,315, dated December 3, 1889. Application filed March l1, 1889. Serial No. 302,878. (No model.)

T0 all whom it Duty concern:

Be it known thatI we, PHINEAs H. ADAMS, Jr., and ORsEMAs T. X. ADAMS, citizens of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Apparatus for Decompos* ing Metallic Salts and Desulphurizing Ores, of which the following is a specification.

The object of our invention is to provide an apparatus for mechanically decomposing metallic salts and their resultingl material, when the substances treated are in a molten condition, by the action of centrifugal force and dividing them into separate and distinct classes 5 and our invention consists in the features and details of construction hereinafter described and claimed.

In the drawing we have shown a vertical `section of our improved apparatus, showing two receiving-vessels arranged in proper relation to each other, together with the supporting-shaft .and running-gear, part of which is in elevation.

In making our improved apparatus for decomposing chemical compounds, metallic salts or salts of metals, and desulphurizing ores we provide two or more receiving-vessels V, adapted to receive the substances to be treated when in a molten condition, and arrange them in such' relation to each other that, while they are separate and distinct from each other and separably rotatable, the material treated is thrown by the action of centrifugal force from one into another.

These receiving-vessels may be made in such a way as will secure the required strength and reduce the conduction of heat from the interior to the exterior. They may be one o1' both surrounded by a curbing and in other respects made so as to best subserve the end in View and permit of their being independently rotated at a high rate of speed for the separation of particles of different degrees of density or specific gravity in the matter treated, so as to separate the particles differing in specific gravity into their respective classes.

Many of the parts and details of construction, vas they do not form the special subjectmatter of our present claims, need not be described in detail, as they will be sufficiently understood from aninspection of the drawing.

As shown' in the drawing, the receivingvessels arearranged in a vertical position 'and in such relation to each other that the neck or mouth of the lower one extends up through the bottom of the upper one. To permit this, the upper receiving-vessel is provided with a bottom containing a hole or opening of a size to permit the neck or mouth of the lower receiving-vessel to be inserted therein, with, preferably, a slight annular space around it. Thisspace should be sufcient to readily and easily permit the neck or mouth of the lower receiving-vessel to be inserted and removed, and to allow it to revolve freely therein without binding or friction. The lower receiving-vessel is mounted u-pon a revoluble actuatingshaft supported and sustained in proper and suitable bearings.

zrlhe upper receivingvessel is provided with a neck or mouth above the neck or mouth of the lower vessel, and preferably of a diameter slightly larger than the diameter of the hole or opening in its bottom, through which the neck or mouth of the lower receiving-vessel is inserted. Itis supported from above by a revoluble actuating-shaft mounted and supported in proper and suitable bearings. Its neck or mouth is preferably provided with side holes or openings, as shown in the drawings, to permit the material thrown od by the action of centrifugal force to be discharged therethrough into an annular tub or other receptacle arranged to receive the same. The revoluble actuating-shaft sustaining the upper receiving-vessel is preferably made hollow, so that the molten material to be treated may be introduced into thereceiving-vessels by flowing down through such hollow actuating-shafts. To prevent the material from coming into contact with the sides of the hollow actuating-shaft, we prefer to insert therein a tube or pipe A, through which the material flows and is kept isolated from the sides of the actuating-shaft itself.

The actuating-shafts of each of the receiving-vessels are provided with lpulleys or beltsurfaces and connected by beltswith pulleys IOO 2 Ii1e,315

or belt-surfaces on power-shafts, or provided with other Suitable means to enable them to be rotated and to rotate the receiving-vessels with their loads of molten materials. By proportionin g the size of the pulleys or belt-surfaces the two aetuating-shatts, with their reeeiv'ingwessels, may be revolved at different rates of speed, as may be desired.

As above said, we prefer to make the neck or mouth of the upper receiving-vessel somewhat larger in diametcrthan the hole or opening in its bottom, through which is inserted the neck or mouth of the lower vessel. This construction will insure the discharge of the material thrown off by the action of centrifugal force and prevent it from escaping from the opening around the neck or mouth of the lower receiving-vessel, and thus insure a constant upward movement of the materia-l be ing introduced and treated, so that it will pass from the bottom ot` the lower receiving vessel to the discharge-openings in the neck or mouth of the upper receiving-vessel.

To permit the upper receiving-vessel. to be emptied withoutdisturbing the lower vessel, means maybe employed to lift it vertically a suiicient distance to enable its bottom to clear the neck or mouth of the upper receiving-vessel, when it may be removed to one side and its contents opened.

Both of the receiving-vessels may be made separable in the plane-of their largest dialneter, so that they maybe opened and the ma terial remaining therein emptied.

lf, now, the two reeeiviug-vessels are arranged as above described and rotated at a l high rate of speed, the molten material falling down upon the bottom of the lower one of the receiving-vessels is immediately thrown by the action of centrifugal force against its sides and walls, where the heaviest particles accumulate in an increasing mass, displacing or forcing out the lighter particles. These lighter particles are carried up and discharged by the action of centrifugal force through the neck or mouth of the lower vessel, when they are immediately carried against the sides of the upper vessel. llere the heavier particles of the matter discharged from the lower vessel will be thrown and accumulate against the sides of the upper vessel, and again displace or crowd out the lighter particles, which are again carried up and discharged by the action of centrifugal force through the holes or openings provided in its neck ormouth. \Ve will thus have the heaviest particles accumulated by themselves in the lower one of the rcceiving-vessels and the lighter particles accumulated by themselves in the upper one of the receiving-vessels, nhile the lightest particles, composed of slag and worthless residue, will for the most part be thrown oft and discharged at the top.

In the drawing we have shown but two recciving-vesscls, and have shown them arranged in a vertical position, which is the position which we prefer.

In our presentapplication the distinguishing feature or principle which we particularly desire to secure is the separation ot' the particles of the material treated into different classes by the employment of two or more receiving-vessels adapted to revolve independcntly of each other, discharging the molten material successively from one into the other by the action of centrifugal force, and thus subjecting it to more than one treatment while still in a molten condition, until the worthless particles are thrown oit and discharged.

\Vhat we regard as new, and desire to secure by Letters Patent, is

l. ln an apparatus for decomposing metallic salts or salts of met-als and desull'ihurizing ores when in a molten state, the combination of a compound or multiplex revoluble receivin g-vessel adapted to receive molten material. to be treated, comprising two or more vessels unconnected and separate from each other, severally rotatable, but in such relation to each other that the material treated is successively carried bythe action of centrifugal force from the vessel in which it is first treated to the next adjacent vessel, to deposit and retain the heaviest particles in each ves' sel in which it is treated, a revoluble actuating-shaft rotating such compound or multiplex vessel as it revolves, and means for rotating the actuating-shaft, substantially as described.
